Omics analysis of factors involving penetration resistance to blast fungus in rice

侵染过程中的侵入阶段是稻瘟病菌对水稻寄主专一性最确定的阶段。虽然水稻的抗渗透性是一种重要的防御反应，但对其了解甚少。本研究利用新一代测序仪对致病性和非致病性稻瘟病菌的基因组结构进行了分析，并对致病性和非致病性稻瘟病菌接种水稻后的蛋白质组和转录组进行了比较。在这里，我们成功地确定了几个重要的候选因素涉及的渗透阻力。这些结果为水稻抗稻瘟病育种提供了基础知识。

The penetration stage during infection process is the most determinate stage for host specificity between rice and blast fungi. Though penetration resistance of rice is an important defense response, it remains poorly understood. In this study, genome structures of pathogenic and nonpathogenic blast fungi were investigated with next-generation sequencer, and proteome and transcriptome of rice was compared, when rice were inoculated with either pathogenic or nonpathogenic blast fungus. Here, we succeeded to determine several important candidate factors involving with penetration resistance. These results will contribute to basic knowledge for breeding of blast-resistance rice.
